Objective: Photobiomodulation therapy is recommended by multiple international societies for managing oral mucositis. These recommendations are based on extensive evidence. However, the search for an optimal photobiomodulation protocol continues. This mapping review focuses on a novel aspect of photobiomodulation therapy which is the immediate effect on pain levels associated with oral ulcerative conditions. Data sources: This literature review systematically compiles and evaluates the evidence about oral mucositis, alongside other oral ulcerative conditions, as the protocols that achieved pain relief for these oral conditions may have potential applicability to oral mucositis management. The scientific database used was PubMed. Conclusion: Whereas most of the randomized controlled trials about photobiomodulation therapy for oral mucositis and other ulcerative oral diseases reported delayed pain relief, certain photobiomodulation therapy protocols reported immediate pain relief. The results of this review highlight the concept of preemptive photobiomodulation therapy, in which photobiomodulation therapy is delivered early in the development of oral mucositis throughout the oncotherapy and may achieve immediate pain relief consistently in most of the patients and close to a negligible pain level. Photobiomodulation therapy, as a powerful nonpharmacologic tool for immediate pain relief, has a great beneficial value in patients suffering from oral mucositis and other painful oral ulcerative diseases such as recurrent aphthous stomatitis and chronic graft-versus-host disease.

Introduction Palliative care, with a focus on enhancing the quality of life for individuals facing life-limiting illnesses, relies on effective pain management as a fundamental component. Opioids, particularly methadone, play a crucial role in addressing moderate to severe pain in palliative care due to their unique pharmacological properties. Methadone, a long-acting opioid agonist and N-methyl-D-aspartate receptor antagonist, is valuable for treating both nociceptive and neuropathic pain. However, the transition to methadone from other opioids requires careful consideration. Objectives This study examines the use of methadone as an alternative to morphine or fentanyl for managing refractory cancer pain in a tertiary care hospital in India. Methods We conducted a retrospective analysis of anonymized medical records of cancer patients initiated on oral methadone for pain management at a tertiary cancer center's palliative medicine outpatient clinic from February 2020 to June 2021. Data included demographic characteristics, pain descriptions, concurrent analgesic use, reasons for transitioning to methadone, rotation methods, methadone dosages, clinical outcomes, adverse effects, and treatment discontinuations. Patients were routinely followed up, with pain scores, morphine equivalent daily doses, and methadone requirements recorded at each visit. Results Forty-four patients received methadone, either as a coanalgesic (41/44) or primary opioid (3/44). Refractory cancer pain, with a neuropathic component, was the predominant indication for methadone use. Following the methadone initiation, all patients experienced significant pain relief. Median daily methadone dose increased from 5 to 7.5 mg after 1 week. Adverse effects were minimal, with one patient experiencing QTc interval prolongation. Patient-specific factors often necessitated deviations from equianalgesic conversion tables in determining methadone dosages. Conclusion Methadone offers a viable option for refractory cancer pain when conventional treatments fall short. Physicians should prioritize personalized titration and thorough assessment during opioid rotation, rather than relying solely on conversion tables. Further research is needed to explore alternative approaches for opioid rotation and to expand our understanding of methadone's optimal use in cancer pain management. [ABSTRACT FROM AUTHOR]

A re‐examination of clinical principles of long‐term opioid therapy (LTOT) for chronic pain is long overdue amid the ongoing opioid crisis. Most patients on LTOT report ineffectiveness (poor pain control, function and health) but still find deprescribing challenging. Although prescribed as analgesics, opioids more likely provide pain relief primarily through reward system actions (enhanced relief and motivation) and placebo effect and less through antinociceptive effects. The unavoidable physiologic LTOT dependence can automatically lead to a paradoxical worsening of pain, disability and medical instability (maladaptive opioid dependence) without addiction due to allostatic opponent neuroadaptations involving reward/antireward and nociceptive/antinociceptive systems. This opioid‐induced chronic pain syndrome (OICP) can persist/progress whether LTOT dose is maintained at the same level, increased, decreased or discontinued. Current conceptualization of LTOT as a straightforward long‐term analgesic therapy appears incongruous in view of the complex mechanisms of opioid action, LTOT dependence and OICP. LTOT can be more appropriately conceptualized as therapeutic induction and maintenance of an adaptive LTOT dependence for functional improvement irrespective of analgesic benefits. Adaptive LTOT dependence should be ideally used for a limited time to achieve maximum functional recovery and deprescribed while maintaining functional gains. Patients on LTOT should be regularly re‐evaluated to identify if maladaptive LTOT dependence with OICP has diminished any functional gains or leads to ineffectiveness. Ineffective LTOT (with maladaptive LTOT dependence) should be modified to make it safer and more effective. An adequately functional life without opioids is the ideal healthy long‐term goal for both LTOT initiation and LTOT modification. [ABSTRACT FROM AUTHOR]

Background: Ovarian endometriosis cysts (OEC) are common chronic diseases occurring in women of reproductive age. Hormone therapy, including the use of oral contraceptives (COCs) and progestins, is widely employed in the treatment of endometriosis and OEC. Objective: This study aims to compare therapeutic effects of long-term daily use of dienogest (DNG, 2 mg) versus drospirenone (DRSP, 3 mg)/ethinyl estradiol (EE, 20 μg) daily on ovarian endometrial cysts, particularly focusing on cysts suppression. Methods: A retrospective analysis was conducted on 84 patients diagnosed with OEC, with 42 receiving DNG and 42 treated with DRSP/EE. After 6 months, assessments were made regarding pain symptoms, size of OEC, tumor markers, and adverse reactions. Results: After 6 months of treatment, both DNG and DRSP/EE effectively alleviated pain in patients with ovarian endometriotic cysts. DNG demonstrated more significant improvements than DRSP/EE in reducing tumor size, mainly in terms of higher drug efficacy and greater percentage of tumor shrinkage. However, DRSP/EE significantly reduced the expression of the tumor markers CA125 and CA199 in our study. Patients taking DNG had a higher likelihood of experiencing side effects than those on DRSP/EE, mainly vaginal bleeding and irregular menstrual periods. Conclusions: Both DNG and DRSP/EE are effective in treating ovarian endometrial cysts. DNG appears to be superior in terms of tumor reduction, while DRSP/EE more significantly decreases the expression of the tumor markers and has fewer side effects. [ABSTRACT FROM AUTHOR]

Introduction: Hip osteoarthritis (OA) is a prevalent and debilitating condition, necessitating effective and safe treatment options. This systematic review aims to explore the potential of intra-articular mesenchymal stem cell (MSC) infiltrations as a therapeutic approach for hip OA. Methods: Following PRISMA guidelines, a systematic review was conducted, encompassing PubMed, Embase, and Cochrane Library databases. Inclusion criteria involved studies focusing on intra-articular MSC injections in patients with hip OA and reporting pain relief as an outcome measure. Quality assessment utilized the Newcastle–Ottawa scale and methodological index for non-randomized studies. Results: Ten studies were included in the review, exhibiting varied designs and sample sizes (316 patients). Outcome measures consisted of cartilage repair assessed through MRI and radiographies, pain scores (WOMAC, VAS, NRS), and functional improvements (HOS-ADL, OHS, FRI, PDQQ, LEFS). The studies reported favorable improvements in functional scores, pain relief, and cartilage repair/radiographic findings, with minimal reported adverse events. Conclusions: Intra-articular MSC infiltrations demonstrate promise as an effective and safe therapeutic intervention for managing hip OA, offering pain relief and functional enhancements. Nevertheless, limited high-quality studies and outcome measure variations underscore the need for further research to establish definitive treatment guidelines. Future investigations should address optimal MSC utilization, long-term outcomes, and potential complications to ensure the success of MSC-based therapies for hip OA management, ultimately improving patient outcomes. The findings provide valuable insights into the potential of MSC-based treatments for hip OA, advocating further rigorous research in this field. Trial Registration: The protocol was registered on PROSPERO database (CRD42023436973). [ABSTRACT FROM AUTHOR]

Background: Lateral epicondylitis impacts 1–3% of the population. It affects nearly half of all tennis players, primarily due to repetitive forearm muscle use leading to pain at the lateral elbow, particularly at the extensor carpi radialis brevis tendon. While conservative treatments resolve most cases, 4–11% of patients with persistent pain require surgery. Tenotomy is the gold standard for repair, but the research comparing the benefits of specific types of tenotomies (open, arthroscopic, percutaneous, ultrasonically assisted, and Tenex forms) is lacking. Methods: PubMed and Embase searches were conducted for articles focused on four tenotomy techniques. The inclusion criteria allowed for the use of randomized controlled trials (RCTs), prospective cohort studies, and comparative observational studies, while the exclusion criteria excluded meta-analyses. Following the PRISMA guidelines, the initial search resulted in 2327 articles. Once the inclusion and exclusion criteria were applied, 1702 articles underwent abstract screening. Finally, 232 articles proceeded to full-text screening, resulting in 37 articles undergoing data extraction. Results: The primary outcomes included functional improvement, pain relief, overall performance, and postoperative disability. The secondary outcomes included patient-reported satisfaction, return-to-work timeframes, and procedural complications. Conclusions: The tenotomy outcomes were similar, regardless of the method, indicating that discussions with patients about their specific outcome preferences may help guide tenotomy method selection.

Background: The SMILE study addresses a significant need in palliative oncology by evaluating the non-inferiority of a shortened, 3-fraction stereotactic body radiotherapy (SBRT) schedule against the traditional 5-fraction approach for non-spine bone metastases in terms of pain control. Optimizing SBRT could significantly enhance the quality of life for patients by providing effective pain relief while minimizing treatment sessions. Methods: This international, multicenter phase III trial will randomize 162 patients to receive either a 3-fraction regimen (9 Gy per fraction) or a standard 5-fraction regimen (7 Gy per fraction). Outcomes, assessed at 3 months post-treatment, will focus on pain response, quality of life, and control of metastasis. With a hypothesis-driven design, the study will incorporate intent-to-treat and per-protocol analyses, incorporating appropriate measures for data integrity and handling of missing information. Discussion: If the 3-fraction SBRT regimen demonstrates non-inferiority, it could streamline palliative care protocols, reduce patient burden, and set a new standard for treatment, reflecting a patient-centered approach in palliative radiation oncology. Trial registration: The trial has been registered prospectively on ClinicalTrials.gov under the identifier NCT05406063, as of May 3, 2022. [ABSTRACT FROM AUTHOR]

Hidradenitis suppurativa is a chronic skin disorder characterized by painful inflammatory nodules and abscesses, significantly impacting patients' quality of life. Current treatment strategies, including topical antibiotics, often yield limited efficacy and pose risks of antibiotic resistance. Photodynamic therapy has emerged as a potential option, with RLP068/Cl (ELKOFAST®, non-sterile formulation) showing promising efficacy due to its broad-spectrum bactericidal activity. We conducted a pilot study assessing the therapeutic response to photodynamic therapy with RLP068/Cl versus topical clindamycin gel in patients affected by hidradenitis suppurativa of Hurley score I, II, and III. Results revealed higher efficacy of photodynamic therapy in combination with RLP068/Cl, particularly in mild cases. Its efficacy remains reliable even in more severe cases when combined with adalimumab. The observed faster lesion improvement and pain relief were ascribed to the bactericidal effects of RLP068/Cl against Gram+ and Gram− bacteria. Furthermore, photoactivated RLP068/Cl was well tolerated with no adverse events reported. Therefore, photodynamic therapy following RLP068/Cl application represents a novel therapeutic option for hidradenitis suppurativa with potential implications for antibiotic stewardship in dermatology.

Background: Recently, enhanced recovery after surgery (ERAS) protocols have attracted attention; they emphasize on avoiding intraoperative hypothermia while performing lumbar fusion surgery. However, none of the studies have reported the protocol for determining the temperature of saline irrigation during biportal endoscopic spine surgery (BESS) procedure. This study evaluated the effectiveness of warm saline irrigation during BESS in acute postoperative pain and inflammatory reactions. Materials and methods: Fifty-five patients who underwent BESS procedure were retrospectively analyzed for the incidence of perioperative hypothermia (< 36oC), postoperative inflammatory factors (white blood cells (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), interleukin-6 (IL-6), serum amyloid A (SAA)), and clinical outcomes (back visual analog scale (VAS) score, postoperative shivering). The patients were divided into the warm and cold saline irrigation groups. Results: Hemoglobin, WBC, ESR, creatine kinase, and creatine kinase-muscle brain levels did not significantly differ between the warm and cold saline groups. The mean CRP, IL-6, and SAA levels were significantly higher in the cold saline group than in the warm saline group (p = 0.0058, 0.0028, and 0.0246, respectively); back VAS scores were also higher with a statistically significant difference until two days postoperatively (p < 0.001). During the entire procedure, the body temperature was significantly lower in the cold saline irrigation group, but the hypothermia incidence rate significantly differed 30 min after the operation was started. Conclusions: Using warm saline irrigation during BESS is beneficial for early recovery after surgery, as it is associated with reduced postoperative pain and complication rates.

Osteoarthritis (OA) is a type of highly prevalent heterogeneous degenerative disease that leads to joint pain, deformity, the destruction of articular cartilage, and eventual disability. The current treatment strategies for OA often suffer from systemic side effects, poor anti-inflammatory efficacy, and persistent pain. To address these issues, we develop light-inducible nanomedicine that enables the co-delivery of anti-inflammatory drug (diacerein, DIA) and small interfering RNA (siRNA) targeting nerve growth factor (NGF) for pain relief to enhance the therapeutic efficacy of OA. The nanomedicine is based on poly(β -amino-ester)-coated gold nanocages (AuNCs), which is further incorporated with the phase-change material (lauric acid/stearic acid, LA/SA). Following intra-articular (IA) injection in vivo , the nanomedicine displays high degree of drug accumulation and retention in the joint lesion of OA mouse models. The photothermal effect, induced by AuNCs, not only promotes DIA and siRNA release, but also upregulates the expression of heat shock protein 70 (HSP-70) to resist the apoptosis of chondrocytes in the inflammatory condition. The internalization of both DIA and siRNA results in strong anti-inflammatory and pain-relieving effects, which greatly contribute to the joint repair of OA mice. This study offers a promising combination strategy for OA treatment. An AuNCs-based nanodrug system was developed for co-delivering anti-inflammatory drug DIA and pain-relieving siNGF to treat OA, enhancing chondrocyte protection and analgesia through photothermal effects and high siRNA transfection efficiency.

Background: The International Classification of Headache Disorders (ICHD-3) uses moderate or severe pain intensity in the diagnostic criterion for migraine. However, few studies have analyzed pain rating on a visual analog scale to identify the numerical intensity that correlates with migraine. Objective: To evaluate the impact of daily self-rated headache pain among patients with either episodic or chronic migraine. This study specifically aims to evaluate the probability of patients labeling their head pain as a headache vs. migraine based on the pain level reported. Methods: A retrospective chart review was conducted on patients with a clinical diagnosis of migraine from July 1, 2014, to July 1, 2019. Results: Data of 114 subjects (57 episodic migraine and 57 chronic migraine) were used for analysis. Patients with episodic migraine on average rated a migraine more severe than a headache (4.1 vs. 6.4; p < 0.001). Patients with chronic migraine on average also rated migraine more severe than a headache (4.3 vs. 6.8; p = 0.0054). Chronic migraine patients transitioned from calling head pain a headache to a migraine significantly later than episodic migraine patients (4.5 vs. 6.8; p < 0.05). Conclusion: A migraine is perceived as having higher pain intensity than a headache in patients with both episodic and chronic migraine. On average, patients with chronic migraine had a higher pain rating at which they report head pain to be considered a migraine. [ABSTRACT FROM AUTHOR]

Background and objectives: Trigeminal Neuralgia (TN) is a debilitating facial pain disorder, often necessitating surgical interventions when medication proves insufficient. Stereotactic Radiosurgery (SRS) is an established therapeutic option. Limited studies explored the feasibility of a third SRS procedure. Our study investigates the safety and efficacy of a third SRS procedure for recurrent TN. Methods: We performed a retrospective analysis across multiple centers using databases collected prospectively. Pain status was evaluated utilizing the BNI Pain Intensity Scales. The Kaplan–Meier method was employed to estimate the time to recurrence, with group comparisons conducted using log-rank tests. Associations were explored using Chi-square and logistic regression models. Results: Ten institutions contributed with a total of 35 patients. A third SRS revealed sustained effectiveness with a pain control rate of 82.7%. The median time to recurrence was 35.5 months. New sensory dysfunction following the third procedure occurred in 22% of patients who had preserved sensory function after the second procedure. When considering those who developed sensory dysfunction after the second procedure, 40% of the entire cohort was affected. There were no significant differences in pain recurrence intervals among the three procedures. A meta-analysis, combining data from previous studies, showed that 89.6% of patients achieved some degree of pain control after a third SRS, with 27.4% experiencing new sensory dysfunction and a median time to recurrence of 31.6 months. Conclusion: Our study, the largest on the topic, affirms the sustained effectiveness of a third SRS for TN, providing comparable pain relief to initial procedures. Notably, an extended pain-free interval after the third SRS session was observed. Facial sensory dysfunction emerged as the primary side effect. Larger studies are warranted to explore correlations with demographics and treatment parameters for a comprehensive understanding of repeat SRS in managing recurrent TN. [ABSTRACT FROM AUTHOR]

Background: Osteoporotic vertebral compression fractures (OVCF) severely affect the quality of life in the aged population. Percutaneous vertebroplasty (PVP) alleviates pain and stabilizes vertebrae, but suboptimal bone cement distribution can cause complications. Hence, this study aimed to clarify whether a new technique for PVP, using a curved guide wire, enhances the distribution of bone cement and improves clinical outcomes in patients with OVCF. Methods: Patients with single-segment OVCF underwent PVP or curved guide wire percutaneous vertebroplasty (C-PVP). Propensity score matching (PSM) was employed to balanced the baseline characteristics. The primary outcomes were the visual analog scale (VAS) and Oswestry disability index (ODI) scores. The secondary outcomes included assessments of bone cement distribution, bone cement injection volume, radiological parameters, and general clinical results. Additionally, Complications and adverse events were documented. Results: After PSM analysis, each group comprised 54 patients, which significantly reduced baseline differences. The C-PVP group showed better clinical outcomes compared to the traditional PVP group. One month after surgery, the C-PVP group had significantly lower VAS and ODI scores (p < 0.001). These improvements persisted at six months and the final follow-up. Additionally, bone cement distribution scores were better (p < 0.001), injection volume was higher (p = 0.03), leakage was less frequent (p = 0.02), and adjacent vertebral fractures occurred less frequently (p = 0.04) in the C-PVP group. Radiological parameters and overall clinical outcomes revealed no significant differences between the two groups. Conclusion: The use of curved guide wire in PVP significantly improves bone cement distribution and injection volume, resulting in better clinical efficacy in patients with OVCF.

Background: Chronic pain significantly impacts quality of life and poses substantial public health challenges. Buprenorphine, a synthetic analog of thebaine, is recognized for its potential in managing moderate to severe chronic pain with fewer side effects and a lower incidence of tolerance compared to traditional opioids. Objective: This retrospective study aimed to assess the long-term efficacy and safety of buprenorphine transdermal patches in patients with moderate and severe chronic pain, with a focus on pain relief sustainability and tolerance development. Methods: This retrospective observational study involved 246 patients prescribed buprenorphine transdermal patches. We evaluated changes in pain intensity using the Numeric Rating Scale (NRS), assessed opioid tolerance based on FDA guidelines for morphine-equivalent doses, and measured patientreported outcomes through the Patients' Global Impression of Change (PGIC). Any adverse events were also recorded. Results: Over the 36-month period, there was a significant reduction in NRS scores for both moderate and severe pain patients, demonstrating buprenorphine's sustained analgesic effect. Tolerance measurement indicated that no patients required increases in morphine-equivalent doses that would meet or exceed the FDA's threshold for opioid tolerance (60 mg/day of morphine or equivalent). Additionally, patient satisfaction was high, with the PGIC reflecting significant improvements in pain management and overall wellbeing. The side effects were minimal, with skin reactions and nausea being the most commonly reported but manageable adverse events. Conclusion: The study findings validate the long-term use of buprenorphine transdermal patches as an effective and safe option for chronic pain management, maintaining efficacy without significant tolerance development. These results support the continued and expanded use of buprenorphine in clinical settings, emphasizing its role in reducing the burdens of chronic pain and opioid-related side effects. Further research is encouraged to refine pain management protocols and explore buprenorphine's full potential in diverse patient populations. [ABSTRACT FROM AUTHOR]

Objective: This review aims to synthesize and critically evaluate the existing literature on kratom use and its possible association with induction of psychotic and manic symptoms, in order to identify potential areas for future research that would improve our understanding of the risks of kratom consumption. Methods: An electronic search was performed using five major databases: including PubMed, Scopus, Google Scholar, Web of Science, and PsycINFO. keywords such as kratom, Mitragyna speciosa, mania, psychosis, bipolar disorder, schizophrenia, schizoaffective, case report, and case series. The retrieved articles on initial search were screened based on predefined inclusion and exclusion criteria for this study, and then data synthesis was performed to analyze relevant information from the included studies. Results: Six prior papers were found using (1 case series and 5 case reports). These included 10 cases, involving kratom use association with mania and psychosis. The ages of patients ranged from 28 to 55 years mean age was 38, and (SD 13.74), the majority were males (8 out of 11). Patients had durations of kratom use ranging from 2 wk to 15 years. Significant association was found between kratom use and the worsening of psychotic and manic symptoms in individuals with psychiatric conditions. Conclusions: Our research highlights the possibility of worsening preexisting psychiatric conditions in the context of kratom use. This study emphasizes the need for clinical evaluation of patients for kratom use. Additional research is required to gain a deeper understanding of the potential mental health implications of kratom use, especially among vulnerable populations. [ABSTRACT FROM AUTHOR]

Background: Carpal Tunnel Syndrome (CTS) is a common condition characterized by compression of the median nerve, leading to pain, numbness, and hand dysfunction. Both manual therapy and surgical decompression are widely used interventions, but their comparative effectiveness remains uncertain. Methods: A systematic review and a meta-analysis were conducted to compare the short- and long-term efficacy of manual therapy versus surgery for CTS. Studies were selected based on randomized controlled trials (RCTs) that met the inclusion criteria, focusing on outcomes such as pain intensity, hand function, symptom severity, and quality of life. Data were extracted and analyzed by using standardized tools to assess treatment effects. Results: Five RCTs with a total of 533 participants were included. Manual therapy was more effective for short-term pain relief, with significant improvements at 1 and 3 months compared with surgery. However, at 6 to 12 months, surgical intervention provided greater improvements in hand function and symptom severity. Quality-of-life improvements were similar in both groups. Risk of bias was moderate to low across the studies, with limitations in blinding due to the nature of the interventions. Conclusions: Manual therapy offers effective short-term relief for CTS, making it a viable option for patients with mild to moderate symptoms. Surgery provides more durable, long-term outcomes, particularly for severe cases. The choice of treatment should be individualized, considering patient preferences and symptom severity.

Purpose: Pelvic and sacral bone metastases cause significant morbidity. The primary aim of the study is to thoroughly evaluate the increase in functional capacity resulting from combined RF ablation and cementoplasty surgery applied to malignant bone metastases of the pelvic bones. Methods: Twenty patients who underwent RF ablation and cementoplasty for malign pelvic bone and sacrum metastases between January 2014 and December 2021 were retrospectively identified. The inclusion criteria were having a life expectancy of more than 1 month, being > 18 years old, and having at least 1 month of follow-up. The Visual Anlogue Scale (VAS) pain, Karnofsky Performance Status (KP), and Musculoskelatal Tumor Society (MSTS) scores were calculated. Results: VAS pain values decreased, and KP values increased postoperatively (p = 0.006 and p = 0,013). There was no statistically significant increase in MSTS (p > 0.05). The correlation relationships between lesion filling ratio and VAS pain, KP, and MSTS scores were not statistically significant (p > 0.05). Cement leakage was observed in 5 patients (25.0%), and no symptoms related to this leakage were observed. Conclusion: The pelvic region, given its close proximity to blood vessels, nerves, and joint areas, along with the distinct challenges associated with its surgery, requires separate evaluation. In studies evaluating applications in the isolated pelvic ring region, as in our study, functional gains have been most comprehensively assessed in this study, demonstrating that the procedure results in significant functional improvements.

Simple Summary: In Australia, animal welfare legislation is being reassessed and a number of notable changes have occurred. This article clarifies statements and builds upon a previous article published in 2023, titled "How Well Does Australian Animal Welfare Policy Reflect Scientific Evidence: A Case Study Approach Based on Lamb Marking". In the article, we explore the debate and changes around mandatory pain relief for mulesing of lambs and how this differs between Australian states and territories. The article also looks at how these legislative changes and industry action influence practice and how the interest of the public is represented in animal welfare law. It stresses the need for clear communication, collaboration among stakeholders, and policies based on scientific evidence to improve animal welfare. This commentary provides an update and clarification on the legislative landscape surrounding mulesing in Australia since the publication of the 2023 study, "How Well Does Australian Animal Welfare Policy Reflect Scientific Evidence: A Case Study Approach Based on Lamb Marking". The article explores legislative changes mandating the use of pain relief for mulesing in various states, emphasising Victoria's original role, and highlighting the fragmented state-based legislative approach to animal welfare. It discusses the impact of these legislative changes on industry practices and animal welfare outcomes. The commentary highlights the complexities of policy development in this area, due in part to the diverse and often conflicting interests of stakeholders and the public. It underscores the importance of transparency, stakeholder collaboration, and scientifically informed policymaking to effectively enhance animal welfare standards. [ABSTRACT FROM AUTHOR]

Background: Adequate pain relief during childbirth is a very important issue for women and healthcare providers. This study investigates the effects on maternal and neonatal outcomes of two analgesic methods during labor: water immersion and epidural analgesia. Methods: In this retrospective observational cohort study at a first-level hospital, in Spain, from 2009 to 2019, 1134 women, low-risk singleton and at term pregnancy, were selected. Among them, 567 women used water immersion; 567 women used epidural analgesia for pain control. Maternal outcomes included mode of birth and perineum condition. Neonatal outcomes included 5 min Apgar score, umbilical cord arterial pH, and Neonatal Intensive Care Unit admissions. Chi-square tests and Mann–Whitney U tests, together with their effect sizes (Cramer's V, odds ratio, and Cohen's d) were used to test the main hypotheses. Results: Spontaneous vaginal birth was almost 17 times more likely in the water immersion group (OR = 16.866 [6.540, 43.480], p < 0.001), whereas the odds of having a cesarean birth were almost 40 times higher in the epidural group (OR = 39.346 [3.610, 429.120], p < 0.001). The odds of having an intact perineum were more than two times higher for the water immersion group (OR = 2.606 [1.290, 5.250], p = 0.007), whereas having an episiotomy was more than eight times more likely for the epidural group (OR = 8.307 [2.800, 24.610], p < 0.001). Newborns in the water immersion group showed a better 5 min Apgar score and umbilical cord arterial pH and lower rates in admissions at the Neonatal Intensive Care Unit. Conclusions: Women choosing water immersion as an analgesic method were no more likely to experience adverse outcomes and presented better results than women choosing epidural analgesia.

Background: Non-specific chronic low back pain (CLBP) is a common painful condition and is responsible for different physical disorders. Despite alternative therapies, patients still suffer from persistent pain. Repetitive transcranial magnetic stimulation (rTMS) has provided much evidence of pain reduction, but results have not been examined deeply in CLBP symptoms. Objective: The analgesic effect of rTMS in non-specific CLBP patients was evaluated by the amplitude of low-frequency fluctuation (ALFF) analysis in resting-state fMRI. Material and Methods: In this experimental study, fifteen non-specific CLBP participants (46.87±10.89 years) received 20 Hz rTMS over the motor cortex. The pain intensity and brain functional scan were obtained during pre and post-stimulation for all participants. The ALFF maps of the brain in two scan sessions were identified and the percent-age of pain reduction (PPR%) was determined using paired t-test. Also, correlation analysis was used to find a relationship between ALFFs and pain intensity. Results: Pain intensity was significantly reduced after induced-rTMS in non-specific CLBP (36.22%±13.28, P<0.05). Positive correlation was found between ALFF in the insula (INS) and pain intensity (rpre-rTMS=0.59, rpost-rTMS=0.58) while ALFF in medial prefrontal cortex (mPFC) and pain intensity had negatively correlated (rpre-rTMS=-0.54, rpost-rTMS=-0.56) (P<0.05). ALFF increased in mPFC while INS, thalamus (THA), and supplementary motor area (SMA) showed decremental ALFF followed by rTMS. Conclusion: This study demonstrated that ALFF in INS, THA, mPFC, and SMA is associated with CLBP symptoms and analgesic effects of rTMS. ALFF potentially seems to be a proper objective neuroimaging parameter to link spontaneous brain activity with pain intensity in non-specific CLBP patients. [ABSTRACT FROM AUTHOR]

Abstract Background The SMILE study addresses a significant need in palliative oncology by evaluating the non-inferiority of a shortened, 3-fraction stereotactic body radiotherapy (SBRT) schedule against the traditional 5-fraction approach for non-spine bone metastases in terms of pain control. Optimizing SBRT could significantly enhance the quality of life for patients by providing effective pain relief while minimizing treatment sessions. Methods This international, multicenter phase III trial will randomize 162 patients to receive either a 3-fraction regimen (9 Gy per fraction) or a standard 5-fraction regimen (7 Gy per fraction). Outcomes, assessed at 3 months post-treatment, will focus on pain response, quality of life, and control of metastasis. With a hypothesis-driven design, the study will incorporate intent-to-treat and per-protocol analyses, incorporating appropriate measures for data integrity and handling of missing information. Discussion If the 3-fraction SBRT regimen demonstrates non-inferiority, it could streamline palliative care protocols, reduce patient burden, and set a new standard for treatment, reflecting a patient-centered approach in palliative radiation oncology. Trial registration The trial has been registered prospectively on ClinicalTrials.gov under the identifier NCT05406063, as of May 3, 2022.

Hence, this study aimed to clarify whether a new technique for PVP, using a curved guide wire, enhances the distribution of bone cement and improves clinical outcomes in patients with OVCF. Methods Patients with single-segment OVCF underwent PVP or curved guide wire percutaneous vertebroplasty (C-PVP). Propensity score matching (PSM) was employed to balanced the baseline characteristics. The primary outcomes were the visual analog scale (VAS) and Oswestry disability index (ODI) scores. The secondary outcomes included assessments of bone cement distribution, bone cement injection volume, radiological parameters, and general clinical results. Additionally, Complications and adverse events were documented. Results After PSM analysis, each group comprised 54 patients, which significantly reduced baseline differences. The C-PVP group showed better clinical outcomes compared to the traditional PVP group. One month after surgery, the C-PVP group had significantly lower VAS and ODI scores (p

Abstract Background The International Classification of Headache Disorders (ICHD-3) uses moderate or severe pain intensity in the diagnostic criterion for migraine. However, few studies have analyzed pain rating on a visual analog scale to identify the numerical intensity that correlates with migraine. Objective To evaluate the impact of daily self-rated headache pain among patients with either episodic or chronic migraine. This study specifically aims to evaluate the probability of patients labeling their head pain as a headache vs. migraine based on the pain level reported. Methods A retrospective chart review was conducted on patients with a clinical diagnosis of migraine from July 1, 2014, to July 1, 2019. Results Data of 114 subjects (57 episodic migraine and 57 chronic migraine) were used for analysis. Patients with episodic migraine on average rated a migraine more severe than a headache (4.1 vs. 6.4; p

Background: Non-specific chronic low back pain (CLBP) is a common painful condition and is responsible for different physical disorders. Despite alternative therapies, patients still suffer from persistent pain. Repetitive transcranial magnetic stimulation (rTMS) has provided much evidence of pain reduction, but results have not been examined deeply in CLBP symptoms.Objective: The analgesic effect of rTMS in non-specific CLBP patients was evaluated by the amplitude of low-frequency fluctuation (ALFF) analysis in resting-state fMRI.Material and Methods: In this experimental study, fifteen non-specific CLBP participants (46.87±10.89 years) received 20 Hz rTMS over the motor cortex. The pain intensity and brain functional scan were obtained during pre and post-stimulation for all participants. The ALFF maps of the brain in two scan sessions were identified and the percentage of pain reduction (PPR%) was determined using paired t-test. Also, correlation analysis was used to find a relationship between ALFFs and pain intensity.Results: Pain intensity was significantly reduced after induced-rTMS in non-specific CLBP (36.22%±13.28, P

Given the prevalence of this type of intractable pain (3– 17% of general population), additional therapeutic non-invasive approaches are desired. Magnetic Peripheral Nerve Stimulation (mPNS) delivered at 0.5Hz provides an effective pain relief without side effects. The objective of this randomized, controlled, multi-site clinical trial was to compare long-term safety and efficacy of mPNS in patients with chronic, intractable, post-traumatic or post-surgical neuropathic pain to comprehensive Conventional Medical Management (CMM).Methods: A total of 65 patients with post-traumatic, post-surgical neuropathy were treated within a multicenter, randomized, clinical trial comparing the safety and effectiveness of mPNS + CMM to CMM alone. Patients were randomized 1:1 and followed through 90 days. The primary endpoint is a proportion of responders, 50% or greater reduction in pain at Day 90. The secondary endpoints included the European Quality of Life 5 Dimensions 3 Level (EQ-5D-3L) and Patient Global Impression of Change (PGIC).Results: At 3 months, 71% of subjects were considered responders (> 50% pain relief) in the mPNS + CMM group vs 13% of subjects in the CMM group. The mPNS + CMM group had a mean reduction in VAS scores at Day 90 of 3.8 points (> 50% reduction), while CMM showed less than a 1-point (0.7 point) mean reduction or ~10% reduction (p < 0.0001). The EQ-5D-3L score increased in the mPNS + CMM study group, whereas the CMM group showed no improvement in EQ-5D-3L at Day 90. PGIC responder rates were 80.6% and 4.3% at Day 90 for mPNS + CMM and CMM groups, respectively.Conclusion: mPNS + CMM was superior to CMM in a randomized prospective study when used for treatment of post-traumatic, post-surgical neuropathy. Due to the lack of other effective non-invasive treatments for neuropathic pain, mPNS should be considered much earlier in the treatment algorithm.Keywords: neuropathic pain, noninvasive, cost effective, pain relief, neuropathy

Introduction: Pain management is crucial for improving patients' quality of care. Persistent pain has been linked to higher depression, anxiety, and work-related difficulties. This study aimed to enhance the time to pain relief in the emergency department through triage nurse-initiated analgesia. It evaluated the impact of nurse-led analgesia on patient satisfaction compared to standard pain management at Tikur Anbessa Specialized Hospital and Kidus Paulos Specialized Hospital. Additionally, it compared the time to analgesia between the two hospitals and assessed the effect of nurse-led analgesia on reducing the length of stay for patients with pain. Methods: Using a quasi-experimental design, the study included an intervention group and a control group. Data was collected using an open data kit, and after ensuring data completeness, it was exported to SPSS and Excel for analysis. To assess the effectiveness of the intervention, the time to analgesia was compared between the intervention and control groups using an independent samples t-test. This statistical test allowed for a comparison of the mean time to analgesia between the two groups.Patient satisfaction scores were also compared between the intervention and control groups using the Mann-Whitney U test. Kaplan-Meier curves were employed to compare the time to analgesia between the intervention and control groups within both settings. A point bi-serial correlation analysis was performed to examine the association between the length of stay and the intervention of nurse-led analgesia in both hospital settings. Result and discussion: The study enrolled 179 participants, with a median age of 34 years (range: 9–80) and 67% female. The most common events leading to pain were medical conditions (21%), followed by trauma/quarrel/war, fall accidents, and underlying diseases (15%, 13%, and 13%, respectively). There was a significant correlation between the degree of pain on arrival and time to analgesia. Additionally, a significant correlation (p < 0.01) was found between time to analgesia and patient satisfaction. Conclusion and recommendation: Implementing a nurse-led analgesia protocol in the emergency department is crucial for reducing time to analgesia and improving patient satisfaction. It is recommended to scale up this approach to other healthcare facilities by incorporating it into the nursing practice guidelines of the country.

Introduction: The brain's reward system (RS) reacts differently to pain and its alleviation. This study examined the correlation between RS activity and behavior during both painful and pain-free periods in individuals with primary dysmenorrhea (PDM) to elucidate their varying responses throughout the menstrual cycle. Methods: Ninety-two individuals with PDM and 90 control participants underwent resting-state functional magnetic resonance imaging (rsfMRI) scans during their menstrual and peri-ovulatory phases. Regional homogeneity (ReHo) and amplitude of low-frequency fluctuation (ALFF) analyses were used to evaluate RS responses. Psychological evaluations were conducted using the McGill Pain Questionnaire and the Pain Catastrophizing Scale. Results: ReHo analysis showed higher values in the left putamen and right amygdala of the PDM group during the peri-ovulatory phase compared to the menstrual phase. ALFF analysis revealed lower values in the putamen of the PDM group compared to controls, regardless of phase. ReHo and ALFF values in the putamen, amygdala, and nucleus accumbens were positively correlated with pain scales during menstruation, while ALFF values in the ventral tegmental area inversely correlated with pain intensity. Those with severe PDM (pain intensity ≥7) displayed distinct amygdala ALFF patterns between pain and pain-free phases. PDM participants also had lower ReHo values in the left insula during menstruation, with no direct correlation to pain compared to controls. Discussion: Our study highlights the pivotal role of the RS in dysmenorrhea management, exhibiting varied responses between menstrual discomfort and non-painful periods among individuals with PDM. During menstruation, the RS triggers mechanisms for pain avoidance and cognitive coping strategies, while it transitions to processing rewards during the peri-ovulatory phase. This demonstrates the flexibility of the RS in adapting to the recurring pain experienced by those with PDM. [ABSTRACT FROM AUTHOR]

Patients undergoing lower‐limb orthopedic surgery may experience multiple postoperative complications. Although peripheral nerve stimulation (PNS) is a promising non‐pharmacological approach that has been used in lower‐limb postoperative recovery, the clinical efficacy of PNS remains inconclusive. This study systematically searched three databases (PubMed, Embase, and Cochrane Library) for randomized controlled trials (RCTs) that examined the treatment effects of PNSs in patients who underwent lower‐limb orthopedic surgery up to September 29, 2023. Two investigators independently identified studies, extracted data, and conducted meta‐analyses with Review Manager 5.4. The outcomes were pain relief (measured by reductions in pain intensity and analgesic consumption) and functional improvements (range of motion [ROM] and length of hospitalization [LOH]). A total of 633 patients including 321 in the experimental groups and 312 in the control groups from eight RCTs were included. PNS showed no significant effect on pain intensity, while analgesic consumption was marginally significantly reduced in the experimental group. Furthermore, no significant differences were observed regarding functional improvements in ROM or LOH after the intervention. Although PNS had no significant effect on pain relief or functional improvements, the intervention exhibited a marginally significant reduction in analgesic consumption. Future trials should be conducted with larger sample sizes, longer follow‐up periods, and more varied stimulation parameters. [ABSTRACT FROM AUTHOR]

Background: Labor pain is the nastiest conceivable pain women are involved in during labor and delivery. In this way, the end of labor pain is frequently outlined by myths and equivocalness. Hence, giving a compelling absence of pain in labor remained a challenge specifically in developing countries including Ethiopia. Objectives: This systematic review and meta-analysis aimed to explore the pooled prevalence of labor analgesia and associated factors to pregnant women in Ethiopia. Design: A systematic review and meta-analysis were utilized in agreement with the Preferred Reporting Items for Systematic Reviews. Data Sources: PubMed/Medline, SCOPUS, EMBASE, Web of Science, Google Scholars, and the Cochrane Library and supplemented it with manual were deliberately looked at until January 1–30, 2024. Methods: Two authors independently extricated all principal information utilizing standardized data extraction designs, and the analysis was done utilizing STATA version 17. Heterogeneity over the studies was evaluated utilizing I 2 measurement. The funnel plot and Egger's weighted regression tests were utilized to assess subjective and objective publication biases respectively. Also, the pooled effect of labor pain management and the associations were evaluated utilizing a random-effects model. Results: The general pooled prevalence of labor analgesia in the present study was 23.3% with a (95% confidence interval (CI): 13.5, 33.1). Maternal age (odds ratio (OR): 1.91; 95% CI: 1.11, 2.77), parity of the mother (OR: 0.28; 95% CI: 0.06, 0.63), history of pregnancy misfortune (OR: 0.12; 95% CI: 0.11, 0.36), length of labor (OR: 2.09; 95% CI: 1.06, 3.13), and awareness about labor analgesia (OR: 1.91; 95% CI: 0.34, 3.49) were significantly related with labor analgesia among pregnant women in Ethiopia. Conclusions: The generally pooled prevalence of labor analgesia among pregnant women in Ethiopia was low. Maternal age, parity of the mother, history of pregnancy loss, length of labor, and awareness of labor analgesia were factors influencing labor analgesia among pregnant women in Ethiopia. This finding proposes exceptional consideration to make laboring mothers free of pain by scaling up the strategies and utilizing labor pain administration in a way that universally recognized standards are met.

Objectives: Lumbar spine surgery is a common procedure for treating disabling spine‐related pain. In recent decades, both the number and cost of spine surgeries have increased despite technological advances and modification in surgical technique. For those patients that have continued uncontrolled back and/or lower extremity pain following lumbar spine surgery, spinal cord stimulation (SCS) has emerged as a viable treatment option. However, the impact of lumbar spine surgical history remains largely unstudied. Specifically, the current study considers the impact of number of prior lumbar spine surgeries on pain relief outcomes following SCS implantation. Materials and Methods: We queried the electronic medical record of five separate pain practices for all patients who have undergone a SCS implant between January 1, 2017, and March 1, 2020. Inclusion criteria consisted of any patients with an SCS implant who underwent a prior lumbar spine surgery. The primary outcome was the mean calculated percentage pain relief in patients based on number of prior lumbar spine surgeries. Results: There was a total of 1974 total SCS implant cases identified across five separate pain clinics. There was no difference in mean calculated pain relief in patients with one prior spine surgery versus those with two or more prior spine surgeries (28.2% vs. 25.8%, adjusted β‐coefficient –3.1, 95% CI –8.9 to 2.7, p = 0.290). Similarly, when analyzing number of spine surgeries as a continuous variable, there was no association between number of spine surgeries and calculated pain relief (adjusted β‐coefficient –1.5, 95% CI –4.0 to 1.1, p = 0.257). Additionally, after patients were stratified based on waveform, there was no association between number of prior lumbar spine surgeries (analyzed both as a categorical and continuous variable) and calculated percentage pain relief. Conclusions: This multicentered retrospective study found that there was no significant difference in pain scores in individuals who received SCS following one or more lumbar spine surgeries. Additionally, the waveform of the SCS device had no statistically significant impact on post‐operative pain scores following one or more lumbar spine surgeries. [ABSTRACT FROM AUTHOR]

Background: Endometriosis is known to be a common chronic disease that often affects the quality of life of patients. Especially for deep endometriosis (DE), the most challenging form of the disease, surgery remains an important component of treatment. However, long-term outcomes after surgery are poorly studied. Therefore, we aimed to evaluate the postoperative clinical course of women with DE who underwent surgery, particularly with regard to pain relief, fertility, and re-operations. Methods: Thus, women who underwent surgical treatment for DE between 2005 and 2015 were included in this retrospective questionnaire-based analysis. Results: A total of 87.0% of the patients who underwent surgery for pain reported a postoperative relief of their complaints. Moreover, 44.6% even stated that they were free of pain at the time of the questionnaire. Patients who underwent surgery for infertility and tried to become pregnant postoperatively gave birth to a child in 45.9% of cases. Approximately one-third of the patients had to undergo another surgery because of endometriosis-related symptoms. The main reasons for re-operation were pain and infertility. The median time to re-operation was 2.1 years. Conclusions: In this extraordinarily long follow-up with a remarkable response rate, we show that surgical treatment of DE leads to pain relief and improved fertility in most cases. However, the risk of recurrence and the need for re-operation remains remarkable. [ABSTRACT FROM AUTHOR]

STUDY QUESTION Is virtual reality (VR) an effective non-pharmacological tool to reduce procedural pain during hysterosalpingography (HSG)? SUMMARY ANSWER An HSG with VR does not reduce procedural pain scores compared to an HSG without VR. WHAT IS KNOWN ALREADY An HSG is often experienced as painful and uncomfortable. VR has been proven successful to reduce acute procedural pain during a variety of medical procedures and interventions. STUDY DESIGN, SIZE, DURATION We performed a two-centre open-label randomized controlled trial between January 2021 and October 2022. PARTICIPANTS/MATERIALS, SETTING, METHODS Women scheduled for HSG as part of their infertility work-up were screened for participation. After informed consent, women were randomized between HSG with or without VR. Due to the nature of the intervention, the study was not blinded. VR was administered by a head-mounted device displaying nature movies and/or relaxation exercises. The primary endpoint was procedural pain measured using VAS (scale 0.0–10.0 cm). Procedural pain was divided into overall pain score and peak pain score during the procedure. It was measured immediately after HSG. Secondary endpoints included patient satisfaction, VR preferences, and adverse effects of VR. MAIN RESULTS AND THE ROLE OF CHANCE We included a total of 134 women, 69 to the intervention group (HSG with VR) and 65 to the control group (HSG without VR). The mean VAS for peak pain was 6.80 cm (SD 2.25) in the intervention group versus 6.60 cm (SD 2.40) in the control group (mean difference 0.28 (95% CI −0.57, 1.12), P  = 0.52). The mean VAS for overall pain was 5.00 cm (SD 2.10) in the intervention group versus 4.90 cm (SD 2.13) in the control group (mean difference 0.06 (95% CI −0.71, 0.84), P  = 0.88). The expectation that VR would be a good distraction from pain during HSG was correlated with both overall and peak pain scores. When correcting for this expectation, we found that women in the intervention group reported significantly higher scores, both in peak (adjusted MD 0.58 (95% CI −0.81, 1.97), P  = 0.021) and overall (adjusted MD 0.43 (95% CI −0.84, 1.71), P  = 0.013) pain, compared to the control group. There were no differences in the prevalence of symptoms that were considered as adverse effects of VR. LIMITATIONS, REASONS FOR CAUTION The study was not blinded. Reasons for declining participation in the study were anxiety or wanting full control during HSG, which might have created selection bias. The distraction score possibly indicates that the level of VR immersiveness was not optimal due to the lack of sound and/or the type of VR applications. Future studies should investigate whether more immersive or interactive VR applications could decrease procedural pain scores during HSG. WIDER IMPLICATIONS OF THE FINDINGS Since VR does not reduce procedural pain, this additional tool should not be used during HSG.

Oral ulcerative mucositis (OUM) is common in patients with cancer, particularly in those undergoing chemoradiation therapy. The effective management of OUM is crucial for continuous cancer care and patient well-being. Recent studies have advanced our understanding of the causes, leading to clinical trials toward novel treatments. This review focuses on the contemporary therapeutic landscape, and provides the latest insights into the mechanisms of mucosal healing and pain. Management strategies for OUM in patients with cancer include maintaining good oral hygiene, reducing mucosal irritation against radiation, and using various topical analgesic treatments, including herbal medicines. However, the current management practices have limitations that necessitate the development of more efficacious and novel treatments. Molecular research on transient receptor potential (TRP) channels in the oral mucosa is crucial for understanding the mechanisms of wound healing and pain in patients with OUM. Targeting TRPV3 and TRPV4 can enhance wound healing through re-epithelialization. The suppression of TRPV1, TRPA1, and TRPV4 may be effective in alleviating OUM-induced pain. Research advancements have improved our understanding and potentially led to novel treatments that offer symptomatic relief. This progress highlights the importance of collaborations between clinical researchers and scientists in the development of innovative therapies. [ABSTRACT FROM AUTHOR]

Purpose of this study is to evaluate patient characteristics, treatments and outcomes in bone metastasis radiotherapy practice. Patients for whom radiotherapy for bone metastasis was planned at 26 institutions in Japan between December 2020 and March 2021 were consecutively registered in this prospective, observational study. Study measures included patient characteristics, pain relief, skeletal-related events (SREs), overall survival and incidence of radiation-related adverse events. Pain was evaluated using a numerical rating scale (NRS) from 0 to 10. Irradiated dose was analyzed by the biologically effective dose (BED) assuming α/β = 10. Overall, 232 patients were registered; 224 patients and 302 lesions were fully analyzed. Eastern Cooperative Oncology Group Performance Status was 0/1/2/3/4 in 23%/38%/22%/13%/4%; 59% of patients had spinal metastases and 84% had painful lesions (NRS ≥ 2). BED was <20 Gy (in 27%), 20–30 Gy (24%), 30–40 Gy (36%) and ≥ 40 Gy (13%); 9% of patients were treated by stereotactic body radiotherapy. Grade 3 adverse events occurred in 4% and no grade 4–5 toxicity was reported. Pain relief was achieved in 52% at 2 months. BED is not related to pain relief. The cumulative incidence of SREs was 6.5% (95% confidence interval (CI) 3.1–9.9) at 6 months; no factors were significantly associated with SREs. With spinal lesions, 18% of patients were not ambulatory at baseline and 50% of evaluable patients in this group could walk at 2 months. The 6-month overall survival rate was 70.2% (95% CI 64.2–76.9%). In conclusion, we report real-world details of radiotherapy in bone metastasis. [ABSTRACT FROM AUTHOR]

Introduction: Chronic cancer-related pain from locally recurrent infiltrative cancers within the bony confines of the pelvis is a devastating and hard to manage condition that can be refractory to many conventional pain management methods. Spinal cord stimulation (SCS) is an evolving and safe method of pain management and can be trialled in a quick and well-tolerated operation under local anaesthesia. To date, this has not been reported in the setting of locally recurrent inoperable pelvic cancers. Case description: In the present study, we report two cases of patients with severe back and lower limb pain resulting from recurrent anal and rectal cancers involving the right lumbar and sacral nerve roots as well as the bony sacrum, which severely affected quality of life and daily functioning. Discussion: Following successful SCS, effective pain relief was observed. Conclusion: SCS could represent an effective supplementary or alternative technique to conventional pain management in this challenging group of patients, especially if other available methods have been exhausted.

Objective To compare the efficacy and safety of high-intensity focused ultrasound (HIFU) and radical surgery for non-metastatic pancreatic cancer (PC).Materials and methods We retrospectively analyzed 89 stage I/II/III PC patients who underwent HIFU (n = 43) or surgery (n = 46) at the Third Xiangya Hospital from January 2020 to December 2021. Pain relief, Karnofsky Performance Scale (KPS), overall survival (OS), treatment-related complications and risk factors for OS were assessed.Results There was no significant difference in the pain relief rate at 30 days post-treatment between the two groups. However, compared with the surgery group, the HIFU group showed significantly lower post-treatment VAS scores (p = 0.019). In the surgery group, the KPS at 30 days post-treatment was lower than pretreatment KPS (70 vs 80; p = 0.015). This relationship was reversed in the HIFU group (80 vs 70; p = 0.024). Median OS favored surgery over HIFU (23 vs 10 months; p

This systematic review and meta-analysis aimed to evaluate the efficacy of Low-Level Laser Therapy (LLLT) in the treatment of Rheumatoid Arthritis (RA), focusing on its effects on pain relief, grip strength, and morning stiffness. A comprehensive search was conducted across PubMed, Scopus, and Web of Science, yielding 3,111 articles. After eliminating duplicates and screening titles and abstracts, 94 full-text articles were assessed, and 23 studies met the eligibility criteria for inclusion in the systematic review. Of these, 22 studies were included in the meta-analysis. Data were extracted and analyzed using a random-effects model, with pooled Mean Differences (MD) calculated for the primary outcomes. The meta-analysis revealed that LLLT did not significantly reduce pain compared to placebo (MD = 0.00, 95% CI [-0.09, 0.09], p = 0.97). However, LLLT significantly improved grip strength (MD = -12.38, 95% CI [-17.42, -7.34], p < 0.01) and reduced morning stiffness (MD = -0.84, 95% CI [-1.33, -0.36], p < 0.01), despite substantial heterogeneity in these outcomes. LLLT shows promise in improving grip strength and reducing morning stiffness in RA patients, though it does not significantly impact pain relief. These findings highlight the potential role of LLLT as an adjunctive treatment for RA, with further research needed to optimize treatment protocols and clarify underlying mechanisms.

Endometriosis (EM) is a chronic condition affecting millions of women globally, characterized by the growth of endometrial-like tissue outside the uterus. This review highlights the latest advancements in understanding and treating endometriosis, focusing on new therapeutic strategies aimed at improving patient care. The article briefly discusses the pathogenesis of endometriosis and reviews traditional treatment methods, including hormonal therapies (progestins, GnRH agonists, and oral contraceptives) and surgical interventions. It then explores the limitations of these conventional therapies and delves into newer strategies targeting specific molecular pathways, offering more effective symptom relief with fewer side effects. Emerging treatments that modulate the immune response and reduce inflammation are also examined, along with innovative approaches to pain management, both pharmacological and non-pharmacological. The review further considers alternative and supportive therapies, such as dietary changes, gut microbiota interventions, and complementary treatments like acupuncture, which may improve the overall management of endometriosis. This review emphasizes the shift toward more personalized, holistic care in treating endometriosis, with a focus on emerging therapies like Aromatase Inhibitors, GnRH receptor antagonists, and hormone receptor modulators. These approaches represent a significant advancement in improving the quality of life for women with this condition.

The corrected figures now accurately represent additional therapies prescribed alongside buprenorphine, patient-reported outcomes assessed by the PGIC scale, and trends in morphine-equivalent doses for patients with moderate pain. The authors acknowledge the mistake but clarify that it does not impact the scientific conclusions of the original article. [Extracted from the article]

Introduction. Approximately 21–27% of patients with blood system diseases receive opioid analgesics, with neuropathic pain being one of the most common reasons for prescription. Gabapentin is used as a first-line drug for neuropathic pain (NP), but has been poorly studied in patients with blood system diseases.The objective was to study the effectiveness and safety of gabapentin in patients with blood system diseases with chronic pain.Materials and methods. A single-center, prospective observational study included 24 patients with thrombocytopenia and pain between October 2017 and October 2022. The patients’ age ranged from 18 to 71 years (median 40 years). All patients with blood system diseases: non-tumor blood system diseases (aplastic anemia) in 8% (n = 2), myeloid tumor blood system diseases (acute myeloid leukemia) in 34% (n = 8), lymphoid tumor blood system diseases (acute lymphoblastic leukemia, follicular lymphoma, diffuse B – large cell lymphoma, T-cell lymphomas, multiple myeloma) in 58% (n = 14). All patients had thrombocytopenia less than 150∙109/l, 66% (n = 16) had less than 90∙109/l. All patients were diagnosed with neuropathic pain (NP), localized according to the neuroanatomical distribution and accompanied by sensory disturbances typical of NP. The localization of pain was different, pain predominated in the lower extremities (63% (n = 15), 95% CI: 43 – 79%), caused by peripheral polyneuropathy of predominantly toxic origin (vincristine, bortezomib), and pain was also caused by the course of the underlying disease: cephalalgia and neck pain, this pain was caused by compression of the nerve structures by the lymph nodes, postherpetic neuralgia, trigeminal neuralgia caused by tumor growth. All patients had intractable, high-intensity pain requiring trimeperidine at a dose of 20–40 mg/day. All patients were prescribed gabapentin therapy at a dose of 900–1200 mg/day.Results. When taking gabapentin in the study group of patients (n = 24), already on the 3rd day, there was a clinically and statistically significant decrease in pain intensity: 1) by median: from the initial 6 to 4 points, p = 0.01 (and up to 3 points by 7th day of therapy) and 2) on average: from initial 6.5 to 3.9 points, p = 0.01 (and up to 3.2 points by the 7th day). Stratification of the dynamics of pain intensity reduction by type of blood system disease (BSD) shows that the decrease by day 3 (sustained and further by day 7) was clinically and statistically significant (p = 0.01) for groups of patients with lymphoid and myeloid BSD, and clinically and approximately statistically significant in patients (n = 2) with non-tumor BSD. Analgesic therapy using small doses of gabapentin gave a pronounced, stable positive effect (pain intensity statistically significantly decreased by an average of 50%). After 7 days of gabapentin therapy, a decrease in the opioid dose was noted in 52% of patients. Side effects were dominated by drowsiness 67% (n = 16), dizziness 32% (n = 8).Conclusion. The results of this study indicate that gabapentin is effective in the treatment of chronic neuropathic pain in patients with BSD and is safe when used in minimal/average therapeutic doses within the daily dosing ranges established by the official instructions for use.

PURPOSE This study aimed to examine the effects of incorporating Pilates into the training regimen of elite fencers, focusing on enhancing flexibility and alleviating pain commonly experienced in the sport. METHODS Twenty-five collegiate male elite fencers were stratified into two groups: a fencing training group (FT, n=12, age=18.92±1.08, weight=71.78±7.43 kg, body mass index [BMI]=22.32±2.09 kg/m2) and a fencing-Pilates combined training group (FPT, n=13, age=19.92±0.64, weight=70.97±9.14 kg, BMI=22.61±1.71 kg/m2). Evaluations, including body composition; physical fitness factors; shoulder strength; and joint range of motion in the upper extremities, lower extremities, neck, and spine, were conducted before and after 12 weeks of the intervention. Additionally, examinations of pain catastrophizing and anxiety levels during competitive engagements were performed. RESULTS There were no statistical differences in body composition, physical fitness factors, or upper-limb strength between the FT and FPT groups. However, the FPT group exhibited a notable enhancement in shoulder abduction of the upper limb when holding a sword, in contrast to the unchanged metrics observed in the FT group. The positive impact of Pilates-combined treatment on flexibility extended to the neck; waist; and lower extremities, such as hip flexion, hip extension, hip abduction, medial rotation, and ankle dorsi-flexion, coupled with significant improvements in psychological aspects, such as pain relief and related competition anxiety. CONCLUSIONS This study confirmed that Pilates-combined treatment can have a beneficial effect on improving flexibility and pain in fencers, and verified the effectiveness of Pilates as an auxiliary training method for elite fencers.

Abstract Background Episil® is a nonabsorbable liquid medical material used to coat and protect the mucosa in patients with oral mucositis. A few studies have reported its efficacy in patients with head and neck cancer. However, reports on its use in patients with hematologic malignancies are scarce. Thus, we aimed to evaluate the efficacy of Episil for the treatment of oral mucositis in patients with acute myelogenous leukemia, malignant lymphoma, acute lymphocytic leukemia, multiple myeloma, and myelodysplastic syndrome. Methods Between May 2018 and March 2019, a total of thirty-seven patients with acute myelogenous leukemia, malignant lymphoma, acute lymphocytic leukemia, multiple myeloma, and myelodysplastic syndrome who received Episil® for the treatment of oral mucositis were included in this study. All patients were treated at the Hiroshima Red Cross and Atomic-bomb Surgery Hospital. To determine the severity of oral mucositis, 22 out of the 37 patients were interviewed and compared objectively using the Common Terminology Criteria for Adverse Events, version 3.0. In addition, subjective measures of the effects of oral mucositis were assessed using an original evaluation protocol (a unique evaluation chart specific to the Department of Oral Surgery, Hiroshima Red Cross & Atomic-bomb Survivors Hospital). Results Out of 37 participants recruited in the study, 31 (84%) described the sensation of Episil® as very good or good. Moreover, the severity of mucositis was found to decrease after the use of Episil® in seven patients out of 22 (19%), particularly in those with mucositis at multiple sites. Participants' evaluations revealed pain relief and improvement in speech and feeding functions. Participants with grade 3 mucositis reported a greater improvement in pain relief, speech, and feeding functions than those with grade 2 mucositis. Conclusions This study suggests the efficacy of Episil® in treating oral mucositis in patients with hematologic malignancies, particularly in those with oral mucositis at multiple sites. In addition to pain relief, Episil® may improve speech and feeding functions.

Introduction An analysis of the medical literature devoted to various aspects of transitional lumbosacral vertebrae shows that there are very few publications covering the course of this disease in the pediatric and adolescent population. Aim To study the issues of epidemiology, diagnosis, treatment and prevention of transitional lumbosacral vertebrae in paediatric and adolescent patients based on the analysis of current medical literature and illustrate the material with our own clinical observations. Material and methods To analyze the literature on the topic, 75 papers published between 1984 and 2023 were selected. Among them, there were 7 (9.3 %) domestic literary sources, 68 (90.7 %) were foreign. In the process of searching for scientific articles, the resources of the electronic databases of current medical information PubMed and CyberLeninka were used. Results and discussion The incidence of transitional vertebrae in children and adolescents is 16.8 % of clinical observations, as reported. In the structure of the transitional vertebrae in children, type II of the disease predominates according to the classification Castellvi et al (1984), 43.2 % of cases. The main clinical symptom of the pathology is pain of lumbosacral location, the intensity of which on the visual analog scale in children corresponds to an average of 3.0 points. In adult patients with similar pathology, the average pain intensity measured with the same scale is 7.5 points. The most informative method for diagnosing the disease is computed tomography, which allows obtaining both 3D images and sections at the level of pseudarthrosis between the enlarged transverse process (or processes) of the suprasacral vertebra and the wing of the sacrum. To relieve pain in children with transitional vertebrae, both conservative and surgical methods are used. The most commonly used procedure is pseudarthrectomy. The study of long-term results one year after the intervention allowed us to record the absence of pain in children who underwent surgery. Prevention measures for transitional lumbosacral vertebrae have not been developed. Conclusion The analysis of the published literature shows that transitional vertebrae are a frequently diagnosed pathology in children and adolescents. Current methods of imaging are able to accurately detect not only the presence of the disease, but also to differentiate its type. The main clinical symptom of transitional vertebrae is pain in the lumbosacral spine which is difficult to relieve with conservative therapy. Pseudarthrectomy is the most frequent surgical method of treatment in children and adolescents that provides stable relief of vertebrogenic pain syndrome. Measures for specific prevention of the disease have not been developed.
